Application filed February This invention relates to latch or fastening devices for usein connection with window sashes, and particularly to devices of this class for locking the separate sashes when in open and closed positions; and the object of the invention is to provide a device of the class specified, comprising a mounting plate, a disk rotatably adjustable on the plate and frictionally retained in different/positions of adjustment, a radially eX- tending arm mounted in connection with said disk, and means on said disk and coop crating with said arm for placing said arm under tension to firmly and rigidly support the same in operative position; a further object being to provide a device of the class described including a part cooperating with the arm of the first'named part and mounted in connection with an independent sash whereby the separate sashes may be drawn together laterally in the operation of locking said sashes; and with these and other objects in view, the invention consists in a device of the'class and for the purpose specified, which is simple in construction and operation, efiicient in use, and which is constructed as hereinafter described and claimed.

The invention is fully disclosed in the following specification, of which the accompanying drawing forms apart, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which:

Fig. 1 is a sectional plan view of one side portion of a window frame indicating two sashes therein, and showing two of my improved devices mounted'in position for use.

Fig. 2 is a view similar to 1 but showing only a part of the construction on an enlarged scale, and with parts broken away and in section.

Fig; 3 is a partial section on the line 3-3 of Fig. 1 and on an enlarged scale; and,

Fig. 4is a side view of the construction shown in Figs. 2 and 3 with parts in different positions.

In the drawing, 5 represents the lower sash of a window, 6 the upper sash, and 7 thewindow frame, shown for the purpose of illustrating one use of my invention. At the right of Fig. 1 of the drawing, and in Figs. 2', 3 and 4, I have shown at 8 one of my improved fastening devices eorn'aris tag in the eonstruetion shown, an attaching 17, 1926.- Seria1Nop88fl75.

plate 9 secured to the top face of the lower sash 5 at anydesired point, preferably centrally of thesash, the plate 9 having a flange 10 for engagement with one side face of the sash 5 to relieve the strain on the screws 11 employed for retaining the plate 9'in position. Mounted in connection with the plate 9 and rotatably adjustable thereon is adisk 12 which is-preferab-ly dome-shaped in form, and pivots upon a similar dome portion 13 on the plate'9, the parts being; pivot'ally connected by a rivet 14. The plate 9 is pro vided at spaced points with depressions 15 to receive a downwardly pressed knob 16' on the disk 12 to frictionally retain the disk in different positions of adjustment.

The disk 12 is provided at oppositely disposed points with upwardly directed ears 17 apertured to receive the ends 18 of a yokeshaped arm 19, the outer end of which is fashioned to form a loop 20. The ends 18 of the arm 19 tensionally engage the dome portion of the disk 12 in suchamanner as to normally depress said arm; The central side portions of the arm 19 are preferably curved upwardly as seen at 21, Fig. 4 of the drawing.

The disk 12 is also provided with a keeper 22 to receive the ends of an operating lever 23 which is fashioned from wire to form oppositely disposed loops 24 adjacent the pivoted ends of said lever, outwardly of which are other oppositely disposed loops 25 joined by a radially projecting loop 26 form- I ing a finger piece, by means of which the lever 23 is operated. The loops 25-encircle the side members of the yoke-shaped arm 19 and are adapted to frictionally pass over the curved central portion 21 thereof to raise the free or loop end 20 of the arm 19 in the movement of the lever 23 from the position shown in 4 of the drawing to the position shown in Figs. 1, 2 and 3 of'the drawing, in which last named figures, the arm 19 is supported in a raised position under tension and locked in such position by the lever 23.

I also employ a member 27 which is mounted upon the upper face of the lower edge of the upper sash 6 and is fashioned from sheet metal to form an upwardly directed hook-shaped part 28 composed of two thicknesses of the metal sheet from which the member 27 is formed. The horizontal portion of the hooleshaped part has a down-- w rdly pin which is beveled. at

one side as shown at 30, Fig. 3 of the drawing. The ends of the sheet from which the member 27 is formed extend in opposite directions to form apertured attaching plate parts 31 and 82 through which screws or similar devices 33 may pass in securing the member 27 in position. The beveled face 30 on the pin 29 is on the outer face of said pin with relation to the lower sash, and said pin 29 is adapted to receive the loop 20 on the arm 19. The bevel 3O aids in clamping the sashes 5 and 6 together in the operation of moving the arm 19 into locked position.

The operation of my improved device will be readilyunderstood from the foregoing description when taken in connection with the accompanying drawing and the following statement. It will be understood that the member 27 will be mounted in connection with the sash 6 with the pin 29 thereof in alinement with the axis of the pivot 14 as seen in the drawing, and in proper spaced relation to receive the loop 20 of the arm 19. hen the disk 12, arm 19 and lever 23 are in the position shown in Fig. 4, in which position the arm 19 extends longitudinally of the top rail of the lower sash 5, and it is desired to move the same into operative position to lock the sashes 5 and 6 together, both sashes are moved into closed position and the arm 19 and lever 23 are swung on the pivot 14 into position to bring the loop 20 beneath the pin 29, after which the lever 23 is moved forwardly by grasping the finger loop 26. The forward movement of said lever will raise the arm 19 and pass the loop 20 over the pin 29, and the continued forward movement of the lever 23 will place the arm 19 under tension, forcibly closing both sashes by upward pressure on the upper sash and downward pressure on the lower sash, and said sashes will be drawn together. After the lever 23 has passed over the raised or curved portions 21 on the arm 19, further downward movement of said lever will operate to lock the several parts in operative position. To unlock the sashes, the lever 23 is simply raised by hand, and after frictionally passing over the curved portions 21 of the arm 19 the lever will drop into the position shown in Fig. 4, releasing the loop 20 of the arm 19 from the pin 29, thus permitting the free ro tation of the arm, lever and disk back into the position shown in Fig. 4 or into inoperative position to permit of the opening of either or both of the sashes.

It will be understood that any number of my improved devices may be employed in connection with the sashes of a window, and it will also be understood that I am not nccessarily limited to the specific use of the device herein shown and described. At the left of Fig. 1 of the drawing, I have shown the device employed in the manner of a sash lock, such as shown and described in a prior application filed by me July 11', 1925, and bearing Serial No. 43,897. In the use of the device shown at the left of Fig. 1, I mount in connection with the loop 29 a cushion facing 34 whereby the free or looped end of the arm 19 may frictionally engage the side rail of the upper sash 6. and the parting strip 7 of the window frame, and without marring or defacing said sash or strip. In this form of construction, the lever 23 is employed to raise the arm 19 and support the same in upright position as shown in Fig. 1 of the drawing. out of engagement with the upper sash. By moving the lever 28 forwardly, the arm 1.9 is released and the spring tension thereof forcibly engages the loop end of the arm with the sash and parting strip. In other words, the lever 23 in the use above described is for the purpose of supporting the arm 19 in inoperative position, while the use of the lever 23 in Figs. 2, 3 and 4 of the drawing, moves the arm 19 into operative position and supports the same in such position. It will also be understood that the device shown at theleft of Fig. 1 of the drawing may also be supported with the arm in depressed position when the device assumes an inoperative position; but it is preferred to support said. arm in raised position under tension, whereby the movement of the arm into operative position may be facilitated by simply raising the lever 23.

It will be apparent that my improved device is not limited to the specific uses herein set out, nor am I necessarily limited to the specific structural details herein shown and described, and various changes in and modifications of the construction herein set out may be made within the scope of the appended claims without departing from the spirit of my invention or sacrificing its advantages.
